Using non-silicone defoamers in film coatings offers several unique advantages. The absence of silicone ensures the integrity of the coating is not compromised, leading to a desirable and optimal final product appearance.

Silicone-based defoaming agents can potentially lower the surface tension of the coating to an undesirable level. This can lead to a less stable film or issues with wetting. Non-silicone defoamers prevent this outcome, ensuring a proper coating process.

Silicone in defoamers might lead to defects such as craters, fisheyes, or even poor adhesion. Non-silicone defoamers significantly reduce these risks, ultimately contributing to an improved coating quality.

Non-silicone defoamers have proven to be compatible with many types of coating systems, including water-based, solvent-based, and UV-cured systems. This widespread compatibility allows the versatility of use across numerous applications.

Non-silicone defoaming agents can provide long-term stability and foam control. They are designed to perform over an extended period without diminishing in effectiveness.

Some non-silicone defoamers can contribute to a better gloss in the film coating, enhancing the visual charm of the coated surface.

In conclusion, these special features make non-silicone defoamers a smart choice for film coating applications. However, each coating system can vary significantly, and the choice of defoamer and its dosage should be fine-tuned according to the specific system and end application requirements for a flawless, high-quality finish.
